Effects of electrically large radome on pyramidal horn

In this paper, we have proposed a hybrid method for the analysis of the electrically large radome-enclosed pyramidal horn. The present method combines BI, FEM, MM, and PO together. It takes the full interactions between the antenna and the radome into consideration, and is more accurate than the decoupled analysis of the antenna-radome system. The aperture fields, the radiation patterns, and the S-parameters at the feeding port of the horn show that the radomes have very strong influences on the performances of the pyramidal horn.
